Carpet underlay for stairs/landing

Hi,

I am looking for the "best" underlay for a cormar 100% wool loop carpet for stairs and landing.

For bedrooms i normally use wilsons plushwalk 11mm, but I undertand for stairs and landing, ideally 9mm is best and something that is not PU foam, but maybe I am wrong?

Ideally by "best" something that does have comfort undefoot but is realtively hard wearing?

Thank you,

 

Our go to for stairs is treadaire chromium 9mm

 

does it compare similarly to plushwalk 10mm?

 

No its a lot better
It’s 180kg density and plushwalk is 105. I wouldn’t ever use that in bedrooms.

 

For a 100% wool loop carpet on stairs and landing, a 9mm underlay is a good choice to avoid issues with fitting and durability. Something like a good-quality crumb rubber underlay, such as Duralay Treadmore, would work well. It’s hard-wearing, provides decent comfort underfoot, and is non-PU foam, which is ideal for high-traffic areas like stairs.

 

I’ve worked with wool loop carpets before, and for high-traffic areas like stairs and landing, a dense, non-PU foam underlay like felt or rubber is a great choice
